If you want to play in the battery side of the AI market, I'd recommend those who do the on-going maintenance, becasuse even if AI building stops, those already built will need to be maintaind, repaired, replaced, etc. Quanta Services is a contractor, but they also do a lot of electrical maintenance, but their stock has already been bid up and is +100 PE right now. Shermco is one of the biggest players in the country in this space, but they are private and just got bought by Blackstone.
